Abstract

A coast stop vehicle for automatically stopping a drive source (1) when a predetermined condition holds during the travel of the vehicle includes a drive source control unit (12) adapted to control the automatic stop and the restart of the drive source (1), a transmission mechanism (2, 4) provided between the drive source (1) and drive wheels (7), and a transmission control unit (12) adapted to control a speed ratio of the transmission mechanism (2, 4). When the drive source (1) is restarted, the transmission control unit (12) is adapted to control the transmission mechanism (2, 4) to a speed ratio higher than a predetermined speed ratio in response to an input shift request to the predetermined speed ratio, and the drive source control unit (12) is adapted to restart the drive source (1) in a state where the speed ratio of the transmission mechanism (2, 4) is higher than the predetermined speed ratio.
